suspension upgrades needed for over 500hp?

[ricergribbs]

my friend has a 1969 chevelle with a 454. currently it has around 450hp but he wants to build it up to around 750hp. hes got a t-10 transmission and a 3.73 posi rear end. what kind of supension/chasis upgrades would he need to keep the car from drifting sideways when he floors it? hes getting ladder bars?

ladder bars wont help, try alston racing in antioch illinois, there tubular suspension components are rated to 2000 HP blown alcohol cars.

woops sorry, thats supposed to say that hes not getting ladder bars, mainly cause they wont fit with his new exhaust lol. oh well, ok ill tell him to check that place out, thanks.
